I want to make a formula one car at least 30 cm in length out of standard LEGO parts. None of the LEGO wheels I have are big enough for this scale. Where can I get some big wheels that would look ok? The big tires here are too big. I looked on BrickLink, but just got confused.

30mm diameter wheels seems small for a 30cm car, to be honest – Joubarc Nov 3 '11 at 6:04
You are probably right. I may have to scale it down a bit to fit the wheels. – Andy Brice Nov 3 '11 at 8:49

You may want to have a look at some official LEGO sets of that scal to check what LEGO has been using.

For example, 2556-1 — SHELL Promotional Set F1 Ferrari seems to be about that length and uses 49mm diameter wheels and tires.

A similar wheel can be found in more recent sets, such as 8041 — Race Truck, which may be cheaper.

You can also look in the specific section for wheels on BrickLink for other sizes.

Ok, thanks. There are a some of those on bricklink, but rather pricey. Do they fit a standard technics axle? – Andy Brice Nov 3 '11 at 8:48

Wheel 30.4 x 14 VR with the tire is ~3 cm (the 30.4 and 14 is mm). It also looks good for sports cars.

Worth noting that the units are millimeters in the descriptions, right? – Erik Olson Nov 2 '11 at 23:59
